What do flashing lights on the rear window wiper and ac buttons mean on a '98 Plymouth Voyager van?

My 97 Voyager has done the same thing. It was control panel programing, the following instructions is how to program your control panel: 1) SET BLOWER ON HIGH 2) SET MODE TO PANEL 3) SET TEMP TO COLD 4) PRESS WASH AND REAR WIPER TOGATHER AND HOLD FOR 5 SEC. IT WILL GO THROUGH A SERIES OF FLASHING, WHEN DONE THE REAR WIPER SHOULD BE THE ONLY ONE FLASHING PRESS REAR WIPER TO EXIT.

DO THIS WITH VAN RUNNING. This worked for my 1997 Voyager. I hope it works for yours.

I followed instructions and it worked( 98 VOYAGER ) BUT I MIGHT ADD THIS; you must wait 30-60 seconds for all the lights except the rear wiper light to go out before you hit the rear wiper button.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
